Hello everyone.
I recently bought it 98 zj (from my mom) as an extra vehicle, has 225,000 miles had a rattle in the cat (exhaust crimped above chunk). Removed cat and thought I had secured downstream 02sensor harness,02 wires melted/shorted to exhaust!
Traced down to fuel pump relay,will crank when jumped at relay but soon after stumbles and dies (exhaust has horrible eye burning fumes)
Has àny other jackwagon done this?
Thanks for any input

 

It's against the forum rules to talk/ speak of and against the federal law to remove the catalyst converters. Put the cat back on and fix the o2 sensors properly

 

It will continue with that problem until you correct the problems posted above, the CPU is getting that information because of those.
